Additional file 1:

Nucleotide sequences used for analysis. The given file contains sequences downloaded from the public database for angiosperms
and few of the gymnosperms. It also contains assembled consensus sequences for gymnosperms.
These sequences were used for getting amino acid as well as codons for evolutionary
analysis. Primers specific to PtPAL were designed using PtPAL1 to PtPAL4.
